Nearly 13 years after Congress created a biosimilars path to bring competition to the U.S. biologics market, new rules of the road are coming into play, via the Inflation Reduction Act (IRA), that could change the course for biosimilars in the long haul – if the IRA’s prescription drug price negotiation mandate withstands numerous constitutional challenges.

With the biggest biosimilar launch in the U.S. just days away, Humira’s (adalimumab) record-breaking ride is quickly slowing down, but the Abbvie Inc. mega-blockbuster immunology drug is nowhere near the end of its road. Meanwhile, the U.S. journey is just beginning for the eight adalimumab biosimilars that could come to market as early as July 1 through licensing agreements with Abbvie. Besides revving their engines against Humira, the new launches will be looking to overtake Amgen Inc.’s biosimilar, Amjevita, which got a five-month headstart in the U.S., thanks to the first-mover status Amgen earned for being the first to sign a licensing agreement with Abbvie.

Many industry watchers are looking to 2023’s Humira biosimilar launch in the U.S. as a portent of the future of biosimilars. While it should help raise awareness of biosimilars in general and produce savings in the immunology sector, its distinctness could make it an outlier in the world of current and future biosimilar competition.

News that the U.S. FTC is finally going to reexamine the role of pharmaceutical benefit managers (PBMs) and their impact on prescription drug prices and availability is playing to applause from several sectors that have been complaining for years about PBM practices.
